but very nearly the same size and mass as planets.
Asteroids are smaller than planets. A few of the asteroids are fairly large; Ceres, for example, is a "dwarf planet" that's bigger than Pluto. But many of the asteroids are a few miles, or a few dozen miles, across. That isn't very big, compared to Mars or Earth.
